ROTOR DISC, ROTOR ASSEMBLY, SYNCHRONOUS MACHINE, AND METHOD OF PRODUCING THEREOF

摘要

The present invention relates to rotor assemblies (1) of synchronous machines (100) and manufacturing method for the rotor assemblies, in particular to rotor assemblies with press-fitting elements which provide improved bonding of rotor discs. Some of the press-fitting elements (10a-10d; 12a-12d; 52a-52d) are positioned close to the outer circumference of the rotor discs, i.e. at positions between 3/4 the radius and the radius, and some (11a-11d; 55a-55d) are positioned closer to the axis of rotation, i.e., at positions smaller than 3/4 of the radius.
